Multi-cellular organisms rely on coordinated and interdependent internal systems to respond to changes to their environment (ACSSU175)

Elaborations
  • describing how the requirements for life (for example oxygen, nutrients, water and removal of waste) are provided through the coordinated function of body systems such as the respiratory, circulatory, digestive, nervous and excretory systems
  • explaining how body systems work together to maintain a functioning body using models, flow diagrams or simulations
  • identifying responses using nervous and endocrine systems
  • investigating the response of the body to changes as a result of the presence of micro-organisms
  • investigating the effects on humans of exposure to electromagnetic radiations such as X-rays and microwaves
ScOT terms

Nervous system,  Plant hormones,  Endocrine system,  Immune system,  Homeostasis
